Hardened High-Strength Pins - ![]()
One of the most stressed components in a roller chain is the pins. Of course, this translates over to the connecting link of a chain. Here at DUROCHAIN, each pin in our connecting links undergoes a specific hardening process to improve wear life, strength, and fatigue resistance.
- Max Countour Sideplates -
![]()
Precision made from AISI 1055/ AISI 1541 steel alloy and hardened to 42 - 45 HRC, our unique max contour side plates provide the highest shock load absorption and most extended wear life! The unique design adds additional material to the plate while maintaining the dimensional requirements of the American National Standards Institute (ANSI). DUROCHAIN max contour side plates add strength and wear life to their accompanied chain assembly compared to the standard side plates used by other tier-one chains.
- Unique Rivets -
![]()
On a connecting link, these unique rivets provide superior holding power and high side load capacity. Coupled with a high-grade spring clip for retaining on the opposing side, our connecting links are designed to withstand demanding applications.
- High-Strength Spring Clip -
![]()
Our high-quality spring clips are precision made from the best raw steel material and heat-treated for added strength. The result is a high-hold spring clip that prevents unwanted clip[ failure that would result in the link failing.
- Precision Pin Groove -
![]()
Our precision grooves provide easy installation of spring clip with improved holding power once installed.
- Superior Plate Hole Preparation -
![]()
Regarding the actual holes in the plates, our superior set of processes (precision piercing, shaving, and ball drifting) make our links easy to install and uninstall. Additionally, this provides the smoothest and best pin-to-plate contact possible.
